Update: custom orthotics helped with gait and hip issues. After initial acclimation period I found that while wearing the inserts mostly for extended outdoor activities the benefit lasts all day, even if I prefer to walk barefoot in the house. Feels good to be able to take full, easy strides again. Regarding the other issue - still daily twinges in the TKR knee. Usually not raising to the level of pain, but definitely still not like the remaining good one. But, much to my surprise, I’m halfway to getting over my aggravation with the clicking noise and feeling. Perhaps my hearing is going as well? Just kidding. All in all, things are pretty good right now. Can always be better, of course, but could also have been much, much worse.
